Emissions from brake pads on EVs are almost non existent (regen braking). This is a vast departure from combustion powered vehicles where PM from braking systems, from exhaust catalytic converters etc. etc. contribute a lot of the grime you see at the edge of a motorway. EVs do make this better.

Tire emissions are NOT a factor we need to be concerned with however :-) Tire manufacture, sure. From waste - most definitely. But emissions from driving are not something to worry about even with the billions of miles driven annually on tires.

Last time I looked at PM2.5 I found the source below[1]. Which lists PM2.5 from tire wear at 0.001 gm per miles. Which is less than brake wear at 0.003. Notable that as you said EV's have much less brake wear.

[1] Was a lot harder to find it again because someones running an SEO agitprop campaign to blame PM2.5 on tires instead of diesel exhaust. I had wade through GIS pages of trash websites to find it again.

Yeah that looks about right. Brake pad PM2.5 is 3x that of tires but both pale into insignificance next to exhaust PM2.5 at almost 10x that of brake pad and tire emissions added together.

The nice thing about EVs is those exhaust emissions are moved away from the tailpipe in populated areas to power generation facilities.

The efficiency of electric vehicles is almost 3x that of the gasoline cycle of drilling, transporting, distilling, transporting again, combusting then achieving almost 30% motion from the chemical energy of gas.

So because of this efficiency there’s just less emissions overall even though the emissions are away from population centres.

Then lastly, the emissions are consolidated in one place so capture and cleaning becomes viable.

EVs are not perfect but they are so much better than gasoline powered vehicles that if you can at all accomodate the switch, then it would be great to consider it.
